This PSU with specific filtering module combo can replace the original switching power supply of the 2018 Mac mini.  The internal power filtering module is specifically designed for the 2018 Mac Mini. It uses high quality parts and three stages ripple filtering (L-C-L-C-L-C) to reduce the power noise.  It also uses high quality silver plated wires for connecting the Mac Mini board.
With this well designed PSU and internal filtering module combo, the smoothness, cleanness and background darkness of sound stage are greatly improved in all aspects.   The different sound stage with this combo can not be obtained from general switching power supply.  The new sound stage is vital, dynamic and clean instead of the original cold and hard feeling using switching power supply.
This modification is also very simple.
